APG stocks the V75254, an AS568-254 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 5.484 in (139.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.762 in (146.35 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. The material holds up against engine and transmission fluids, chlorinated solvents, and petroleum oils and fuels. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or ketones and esters are present.
Maintenance and OEM teams specify it across oil and gas, semiconductor equipment, and automotive fuel systems.
Stocked as V75254 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
